The quartet of skipper Phil Heseltine and crew Aaron Hawkins and father and son Greg and Jack Densem won the Noelex 25 championships on Otago Harbour.
The crew sailed the boat Simba, owned by Heseltine, to victory through its consistency on the water.
The championships involved nine races, with five different winners.
But on the first day of the three-day regatta, the crew of Simba bagged two first placings and three second placings, which gave them a real head start.
They hung in there throughout the regatta and, when the final race started, they had to finish in the first four.
They duly did that and won the title.
Heseltine said it was great to have a victory in the regatta, especially when it was the first time the crew had won a national title.
``Everyone chipped in really well.
``We'd put some new sails on the boat and they had worked a treat.
``I used to sail with Greg quite regularly and the crew all worked well together,'' Heseltine said.
The Noelex 25 is a boat which was designed and constructed in the mid to late-1970s and into the 1980s.
It is a trailer yacht designed to handle all seas.
It was very popular for a while before production stopped in New Zealand. It was shifted to Australia where eventually production was stopped.
It is liked by many sailors due to its good handling and ability to be sailed shorthanded or by family crews.
It is very good in heavy seas and also has a small sail wardrobe.
For Simba - the boat was named by Heseltine's young son - the conditions in lower Portobello Bay proved to its liking.
It was also something of an emotional win for Greg and Jack Densem.
Jack (15), a year 12 pupil at Otago Boys' High School, teamed up with his father to win.
Greg, a teacher at Otago Boys' High School, said it was quite special to win the championship.
``It's not often you can team up with your son, at 47, get to compete nationally, and then win.''
